An important question in multi-radio multi-channel and multi-hop networks is how to perform efficient network-wide broadcast. Currently almost all broadcasting protocols assume a single-radio single-channel network model. Simply using them in multi-channel environment without careful enhancement will result in unnecessary redundancy. In this paper, we focus on reducing the amount of redundant t...

Terrestrial digital broadcasting services in Japan will start in 2003, and conventional analog broadcasting will be terminated in 2011. However, it has been reported that the mobile reception quality for the terrestrial digital broadcasting is significantly reduced for high bit rate transmissions such as high definition television broadcasting. In this study, the reception quality of terrestria...

The paper explores the valuation of radio spectrum granted by the State to radio operators for radio program broadcasting. Radio spectrum may be one of the most tightly regulated resources of all time, since every wireless device, from mobile phones to traditional radio devices, depends on access to the radio frequency wireless spectrum. Due to the scarcity of radio spectrum, the available numb...

We study the communication primitives of broadcasting (one-to-all communication) and gossiping (all-to-all communication) in known topology radio networks, i.e., where for each primitive the schedule of transmissions is precomputed based on full knowledge about the size and the topology of the network. We show that gossiping can be completed in O(D+ Δ log n logΔ−log log n ) time units in any ra...

Digital multimedia broadcasting is available in more and more countries with various forms. One of the most successful forms is Digital Video Broadcasting for Terrestrial (DVB-T), which has been deployed in most countries of the world for years. In order to bring the digital multimedia broadcasting services to battery-powered handheld receivers in a mobile environment, Digital Video Broadcastin...

In parallel, broadcasting has changed rapidly with the changing of the world at the same area. Broadcasting is also influenced and reshaped in terms of the emergence of new communication technologies. These developments have resulted a lot of economic and social consequences. The most important consequences of these results are those of the powers of the governments to control over the means of...
